Create a graphic with graphgdiplus udf with time axis

[badeend 0]

Hi,

 

I'm trying to create a graphic with a time axis from an excel file. 

I had to change the times to timepassed in seconds because otherwise i could not get the graphic to plot like i wanted.

This could work on a cleaner way but i can't fix it.

The big question i'm having is if i can get the handle from the lines i plot so that when i plot (for example) 8 i can select which ones i can show on the graph.

Or is the only way to do this plot the graphic again every time with the lines that i want to visualize.

The excel contains the following data for now :

column 1: value1 to be plotted

column2: date of all the values

column3: empty (i use this in my code)

column4: value2 to be plotted

1143,186

I added my code after this. Thanks for any help!!

Did you have a look at my ExcelChart UDF?
Makes creating charts much easier including exporting in another format.

Thanks, i'll look in to it. 

Problem is that i would like to move away from excel. 

I would like to make the chart in autoit and get the data directly from our sqlserver.

The problem is that i'm not so good at autoit so i would like to make each part individually to see if i can do it and if so create the whole program.

Thanks for your response!

You can use Excel to store the data or retrieve it from SQL.
ExcelChart doesn't mind where the data comes from. The UDF just takes some data and visualizes it.
