Query on Time Series Charts...!

[Chaitanya]

Hi,
I am displaying a time series chart and a bar chart in the same chart, in this case I a musing CombinedDomainXYPlot for placing the timeseries chart and bar chart; what is happening in this case is that the values in the X-axis are not repeating themselves for both the charts, how can I do so?

thanks.

I'm not sure what you mean - can you post a screenshot or the source code for a small self-contained demo?

Hi Gilbert,
thanks for resonding, the code segment is as below.
Here you will see the values in X-axis Jan , Feb, Mar so on... are appearing in the sub plot below and not in the subplot above.

Hi Gilbert,
Its very urgent for me to fix this prob. if possible please give me sol as early as possible.
Here you will see the values in X-axis as Jan , Feb, Mar so on... are appearing in the sub plot below and not in the subplot above.
how do I acheive this???
Please help...
