I made a dataset like below..
=============================
Day | 10/17, 10/18, 10/19
A | 10 14 23
B | 5 6 7
C | 5 6 7
And I created the stack column chart with this data.
I want the each box has its original value. but default chart print the accumulated value at each box.
In case of 10/17 data. Ultra chart draw the label with 10, 15, 20.
How can I change the accumulated value with the original value?
P.S. please use c# at reply.
You need to set the format string to "<DATA_VALUE_ITEM>" instead of "<DATA_VALUE>"I'm assuming you're using a ChartTextAppearance object for this?ChartTextAppearance chartText = new ChartTextAppearance();chartText.ItemFormatString = "<DATA_VALUE_ITEM>";chartText.Visible = true;chartText.Row = -2;chartText.Column = -2;this.ultraChart1.ColumnChart.ChartText.Add(chartText);
