I want to show the bar chart in y axis 've a date values and x axis 've a country value. pls any one tell this.....
I am not sure I follow on what you are trying to do. Can you provide a sample QVW and any screenshot of what you are trying to accomplish?
Y-axis int his bar chart are the aggregation results, meaning a value range between 0-80. You can not have a non-numeric value as the Y-axis, or do you have a suggestion on what that chart should look like?
For the X-axis values and legend values, you control that with the order of the dimensions in the chart.
I do not understand what you intend the chart to look like. Do you have any example image of a similar chart from some other program or webpage as reference?
If you have country as X-axis it means that you have your aggregation result scale on the Y-axis. What is your expression if dates become the Y-axis?
How about transforming this into a Grid Chart? That chart type allows you to put a dimension on either axis, and show the result of the expression as a circular area that grows with the expression value.
Or as a bunch of pies in a bakery
This screenshot is from the document "Data Visualization.qvw" that is included with every QV Desktop Installation. It shows you how it's done.
