Hello
I have custom data source for the graph, I'm generating date range records.
Some dates might not have any results and I would like this to be reflected in the graph.
Currently, If I return null in any of the dataset rows the graph assumes this is null, also another strange behavior, for the following data
row1,null
row2,null
row3,null
row4,500
row5,null
row6,12
...
The drawn graph shows linear growth from row1 to row4 which is obviously not true, it should show very steep growth and decrease on row4. If I replace the null's with 0's the graph does show the steep growth and decrease as expected but then I can't tell "no data" from actual 0 for current row.
Thank you,
Maxim.
