Question

VB Controls: Is it possible to change datapointlabels in MS Chart

Asked by: bobweather

I'm using VB6 and have been so far successful in using the MSchart control for charts.  I'm using MS Chart Control 6.0 (OLEDB).

I have loaded the data as follows

  frmChart.MSChart1.ChartData = arrChartData.

My question is:  Can I change the existing datapointlabels of a series?

I have tries to use the following code, but I get an error saying the index is out of bounds.

.Plot.SeriesCollection(1).DataPoints(1).DataPointLabel.Text = "546"

I have tried iterations with DataPoints.Item(1).DataPointLabel.Text = "546" but I get the same error.

Is it possible to access the individual datapoints?

Many thanks in advance for your help.
