(UPDATE 12/04/07: Çox maraqlı bir web hissəsi vasitəsilə bu müraciət ki, bir blog keçid sonunda bir maraqlı resurs Əlavə)

This blog entry describes how to create a bar graph in SharePoint. This works in both WSS and MOSS environments as it only depends upon the data view web part.

The overall approach is as follows:

  1. Create a list or document library that contains the data you want to graph.
  2. Place the associated document library / custom list onto a page and convert it to a data view web part (DVWP).
  3. Modify the DVWP’s XSL to generate HTML that shows as a graph.

Biznes Ssenari / Setup:

Mən standart Title sütun və bir əlavə sütun ilə xüsusi bir siyahısını yaratdıq,,en,"Status",,en,bu modellər,,en,çox simplistically,,en,Xərcləri üçün bir "Avtorizasiya,,en,title layihə və statusu siyahıdan bir dəyər təmsil ssenari,,en,Təklif olunan,,en,Prosesində,,en,dayandırılıbdır,,en,obyektiv, bu status kodları göstərir ki, interaktiv üfüqi bar grafik istehsal edir,,en,Mən siyahısını əhalisi var və bu kimi görünür,,en,Data View Web Part yarat,,en,Bir səhifə üçün xüsusi siyahı əlavə DVWP yarat,,en,mənim halda site səhifə,,en,və təlimatlara əməl edin,,en,Bundan əlavə, sadəcə DVWP yaratmaq üçün,,en,biz də bütün mövcud satır göstərmək paging əmlak qurmaq lazımdır,,en,bu kimi bir şey görünür,,en,Mən həmişə yaxın SPD və browser,,en,Mən browser istifadə edərək səhifə yenidən açmaq,,en, "Status". This models (very simplistically) an "Authorization For Expense" scenario where the title represents the project and the Status a value from the list of:

  • Proposed
  • In Process
  • Stalled

The objective is to produce an interactive horizontal bar graph that shows these status codes.

I have populated the list and it looks like this:

Create Data View Web Part:

Create the DVWP by adding the custom list to a page (site page in my case) and follow the instructions burada (http://paulgalvin.spaces.live.com/blog/cns!1CC1EDB3DAA9B8AA!395.entry).

In addition to simply creating the DVWP, we also need to set the paging property to show all available rows. Mənim üçün, this looks something like this:

Bu noktada, I always close SPD and the browser. I then re-open the page using the browser. This avoids accidentally mucking up the web part layout on the page.

Modify the XSLT:

It’s now time to modify the XSLT.

I always use visual studio for this. (Görmək burada for an important note about intellisense that will help you a lot).

I create an empty project add four new files (replacing the words "Original" and "New" as appropriate):

  • Original.xslt
  • New.xslt
  • Original Params.xml
  • New Params.xml

Mənə gəldikdə isə, bu kimi görünür:

image

Modify the web part and copy the params and XSL to the "Original" version in Visual Studio.

The objective here is to cause the XSL to transform the results we get back from the DVWP query into HTML that renders as a graph.

Bu məqsədlə, it helps to first consider what the HTML should look like before we get confused by the insanity that is known as "XSL". (To be clear, the following is simply an example; don’t type it or copy/paste into visual studio. I provide a full blow starting point for that later in the write-up). The following sample graph is rendered as per the HTML immediately following:

Sample Bar Graph

Corresponding HTML:

<html>
<orqan>
<mərkəz>
<table width=80%>
<tr><TD><mərkəz>Horizontal Bar Graph</TD></tr>
<tr>
<td align="center">
<table border="1" width=80%>
<tr>
<td width=10%>Open</TD>
<TD><table cellpadding="0" cellspacing="0" border=0 width=50%><tr bgcolor = red><TD>&nbsp;</TD></tr></masa></TD>
</tr>
<tr>
<td width=10%>Qapalı</TD>
<TD><table cellpadding="0" cellspacing="0" border=0 width=25%><tr bgcolor = red><TD>&nbsp;</TD></tr></masa></TD>
</tr>
<tr>
<td width=10%>Stalled</TD>
<TD><table cellpadding="0" cellspacing="0" border=0 width=25%><tr bgcolor = red><TD>&nbsp;</TD></tr></masa></TD>
</tr>
</masa>
</TD>
</tr>
</masa>
</orqan>
</html>

I used a dead simple approach to creating my bars by setting the background color of a row to "red".

The take-away here is this: Sonda, all we are doing is creating HTML with rows and columns.

Template XSLT:

I’ve copied the XSLT that generates a horizontal bar graph. It’s fairly well commented so I won’t add much here except for these notes:

  • I started with the default XSL that SharePoint Designer gave me when I first created the DVWP.
  • I was able to cut this down from SPD’s 657 lines to 166 lines.
  • I didn’t mess around with the parameters XML file (which is separate from the XSL and you’ll know what I mean when you go to modify the DVWP itself; there are two files you can modify). Lakin, in order to simplify it, I did remove nearly all of them from the XSL. This means that if you want to make use of those parameters, you just need to add their variable definitions back to the XSL. That will be easy since you will have the original XSL variable definitions in your visual studio project.
  • You ought to be able to copy and paste this directly into your visual studio project. Sonra, remove my calls and insert your own calls to "ShowBar".
  • The drill down works by creating an <a href> like this: http://server/List?FilterField1=fieldname&FilterValue1=actualFilterValue. This technique may be of value in other contexts. Əvvəlcə, I thought I would need to conform to a more complex format: http://server/List/AllItems.aspx?View={guid}&FilterField1=blah&FilterValue1=blah, but in my environment that is not necessary. The List’s URL is passed to us by SharePoint so this is quite easy to generalize.

Here it is:

Concluding Thoughts:

Can This Be Generalized?

I love this graphing concept, but I hate the fact that I have to go in and do so much hand-coding. I’ve given a little thought to whether it can be generalized and I’m optimistic, but I’m also a little fearful that there may be a brick wall somewhere along the path that won’t offer any work-around. If anyone has some good ideas on this, please make a note in the comments or Mənə e-poçt.

Vertical Graphs:

This is a horizontal bar graph. It’s certainly possible to create a vertical graph. We just need to change the HTML. I would start the same way: Create an HTML representation of a vertical bar graph and then figure out how to get that via XSL. If anyone is interested in that, I could be persuaded to try it out and work out the kinks. If someone has already done that, please let me know and I’ll gladly link to your blog 🙂

I think that challenge with a vertical graph is that the labels for the graph are more difficult to manage, but certainly not impossible.

Field Name Gotcha’s:

There are at least two things to look out for with your field names.

Ilk, a field name with a space has to be escaped in the XSL. This will probably be an issue here:

        <XSL:dəyişən ad="totalProposed" 
 seçmək="count(/dsQueryResponse/Rows/Row[normalize-space(@Status) = 'Proposed'])" />

If your "Status" column is actually named "Status Code" then you need to reference it as "Status_x0020_Code":

   <XSL:dəyişən ad="totalProposed" 
 seçmək="count(/dsQueryResponse/Rows/Row[normalize-space(@Status_x0020_Code) = 'Proposed'])" />

Ikinci, and I’m a little fuzzy on this, but you also need to be on the alert for field name changes. If you name your field "Status Code" and then later on, rename it to "AFE Status", the "internal name" does not change. The internal name will still be "Status Code" and must be referenced as "Status_x0020_Code". The "other resources" links may help diagnose and correct this kind of problem.

About that Color:

I picked "red" because it’s pleasing to me at the moment. It would not be a big deal to show different colors so as to provide more than just a visual description of a number, but to also provide a useful KPI. Məsələn, if the percentage of "stalled" AFE’s is > 10% then show it red, otherwise show it in black. Istifadə <XSL:seçmək> to accomplish this.

Happy transforming!

    This page almost completed the task I was looking for.

    I have a group that wants to use the SharePoint Survey list to create a weekly poll. The catch? They do not want to see code… Or change the system every time they send the poll (planned for a weekly update).

    I was able to connect this to the Survey list and create the graph on the first answer column. What I can’t predict though are the values and labels that they will need moving forward. To make matters worse they may have more or less answers available each week.

    I will look elsewhere just in case, but has anyone found a way to create rows and labels based off of the number of available options and dynamically setting these rather than hard coding the expected values?

    Thanks Paul. Very helpful. Thanks to your work, I was able to add a graph bar column to an existing DVWP (e.g. for tasks) very easily with just a few lines of your code.
    In SharePoint Designer, I inserted a data view with the Title and % complete columns from a task list. I put the cursor in one of the cells and right click. I select insert a column to the right. In code view, I found the <TD> and replaced the <XSL:text element inside the cell with your code:
    <table cellpadding="0" cellspacing="0" border="0"
    width="{round(@PercentComplete*100)+1}%">
    <tr style="background-color:red">
    <XSL:text disable-output-escaping="yes"><![CDATA[&nbsp;]]></XSL:text>
    </tr>
    </masa>

    Note I changed the row color code from bgcolor="red" to style="background-color:red"
    Həmçinin, was able to select one of the columns in my list (@PercentComplete) in place of "$BarPercent"

    Paul, thanks for this! I created an exact copy of what you did and it works almost perfect. There was one tiny issue in row the 2nd paragraph of your code:
    <XSL:template match="/" xmlns:SharePoint="Microsoft.SharePoint.WebControls"
    xmlns:__designer=http://schemas.microsoft.com/WebParts/v2/DataView/designer xmlns:asp="http://schemas.microsoft.com/ASPNET/20"&gt;
    After I corrected that it works like charm! I will now adapt this to my own list and status but I am sure it won’t be to hard. (I will post the result)
    Thanks yenidən

    question –
    What if in my graph, i wanted a variable to not just count one status but count multiple ones?
    Belə, for example what if I had —
    <XSL:variable name="RequestsInitialized"
    select="count(/dsQueryResponse/Rows/Row[normalize-space(@Status)=’WIP’])" />
    –The thing is, I want it to count instances of ‘WIP’, but i also want this variable to count something else like ‘Pending Review’.. how would i do this?

    Hi, I am trying to modify this slightly so that it displays a graph of tasks in a task list against user information. It uses a column called @AssignedTo which is a user presence column. I can get it to display teh rendered HTML but cant get it to calculate and display values.
    Hər hansı bir fikir?

    A question:
    I would like to filter on two fields at the same time: how can this be achieved?
    Məsələn, one of your variables is called totalStalled and it filters on @Status.
    I would like to filter at the same time to reduce my number of returned records on another field.
    I already found how to make an ‘OR’, but I donnot manage to find the ‘AND’
    An ‘OR’ can be achieved like this:
    <XSL:variable name="totalStalled" select="count(/dsQueryResponse/Rows/Row[normalize-space(@Status) = ‘Stalled’] | /dsQueryResponse/Rows/Row[normalize-space(@ExtraFilterField) = ‘value’])" />

    I have a ‘Using Dashboards in SharePoint’ question. We are a military hospital using MOSS standard for our Intranet and would like to build a dashboard for our Command Group to see ‘real time’ if possible. One of the main points is viewing the real-time current workload within the facility and literally watch it change up and down (may have to click “refresh”/F5).

    Thank you in advance,
