side-by-side bar chart editing

Hi,
I have side-by-side bar char which has two y series and 10 values on x-axis.

out of these 10 values, i have to highlight only two bars of one value with different color, and also shows these 2 different color for these values in Legend.

Any suggestions?

Thanks

Hi mh10,

Can you explain a little more in detail? I'm not sure if I'm understanding correctly. Thanks.

Hi Michael, 
Please see attached bar chart from Zip file, which i am trying to create. 
 
In this graph, two bars related to value A, B, C, E has same Green & Red color. But two bars of value D should have Brown & Black color...to hightlight it also symbol 'D' on X-axis should be in bold. 
 
In graph legend also i have to show these four colors as you can see in attached graph file. 
 
 
let me know your opinion 
 
Thanks

mh10,

You can definitely color the two bars different colors initially with the palette. Then, you can use scripting in the beforeDrawDataPoint() function in the chart script to color the two bars for 'D' black and brown. Adding the extra items to the legend is something I haven't done and I'm not sure it's possible to just add them. You might be able to do this by adding a couple more series' to the chart as series 1 and 4 with values of 0, so the bar doesn't show up and then change their title and color in the chart script for the legend. I have not tested this though.
