The version of Spire.XLS that we have (Version: 7.11.13.7040 / Runtime: v4.0.30319) does not have the capability to have a data label value other than the plot point value on a line chart. If it is capable of that, we haven't been able to figure it out. Does the newer version of Spire.XLS support this excel feature?

For instance, a plot point could have a value of, say, "30". The point on the chart shows correctly, but the data label will also show a value of "30". In excel you can have a different Data Label value display even if the plot point is "30". So we'd like to do something along the lines of:

plot point = 30
data label = "today"

We are able to do this in excel, but as soon as Spire.XLS reads the excel file, it converts the data label to also be "30".

Thanks!

Dear snw1969,

Thanks for your inquiry.
Spire.XLS supports to do that, and there are two situations.
1. Change the datalabels of datapoint directly, please refer to following code.
Code: Select all
ChartSerie.DataPoints[i].DataLabels.TextArea.Text = "today";

2. Value from cells.
