Hi,
I have here some data that consists of 7 categories (names) and each
category has 4 values (added, deleted, unchanged and ratio).
When I render the bar chart programmatically, the following stacktrace
is produced:
org.eclipse.birt.chart.exception.ChartException: Horizontal axis
contains 7 objects; vertical axis contains 4 objects

org.eclipse.birt.chart.render.BaseRenderer.validateDataSetCo unt(BaseRenderer.java:2100)

[..]
I have the following code here:
for (int i = 0; i < data.length; i++) {
double [] values = new double[data[i].length];
for (int j = 0; j < data[i].length; j++) {
values[j] = data[i][j];
}
NumberDataSet orthoValues = NumberDataSetImpl.create(values);
// Y-Series
BarSeries barSeries = (BarSeries) BarSeriesImpl.create();
//barSeries.setSeriesIdentifier(series[i]);
barSeries.setSeriesIdentifier("Test");
barSeries.setDataSet(orthoValues);
[...]
}
data is a 2-dim double-array [7][4] and the categories are a list of 7
strings.
What must I do to get this running?
Thanks,
Stefan
