vertical Bar graph in XSL

Hello experts,

I want to know how to write XSL code to draw a bar graph vertically for the below xml.

[----------------------
- <Limits>
<Count Value="501" />
<Bandwidth Value="90.0" />
</Limits>
- <Streaming Status="normal">
<StreamCount Status="normal" Value="5" />
<StreamBandwidth Status="critical" Value="77.0" />
</Streaming>
---------------------]

Graph shoud look like this in table format:

[lable] [rectangle box .......] [value of lable from xml]
[initial value ie '0'] [max. value of lable from xml]

Count *****......................... 5
0 501

Bandwidth *************........ 77.0
0 90.0

Also it would be great to have the rectanlge box fill with color depending on the 'status' of the value.
Here status are:
<StreamCount Status="normal" Value="5" /> ------------------------[normal ie green.gif]
<StreamBandwidth Status="critical" Value="77.0" /> -----------------[critical ie red.gif]

Total 4 color schema: red.gif, green.gif, yellow.gif, organe.gif for critical, normal, warning, unmanaged status.
Depending on the status, the rectanlge box should be occupied by proper 'gif' file.

Regards,
Hyd

Hi Don,

Yes, thsi is want I wanted, but Don there is a problem. Your XSL is working fine with IE browser, and in NS there is no graph picture, just a blank line. Check yourself in both browser.

Plus, would you like to add ur design idea, rite now it seems like ok, but the design not looking fine to me, I mean the way values and graphic is lyed out. Can we rearrange values and text ?? Need ur idea. But graphics has 2b verticaly only.

Also like u hv used: 'background-color:green' or 'background-color:red' can we use 'green.gif' or 'red.gif', plz post me the sytnax.
