 AddMark with multiple datasets |

layer = chart.addBarLayer2()
# loop
layer.addDataSet(values)
Now, I want to highlight certain values in the dataset, but as far as I can tell
c.xAxis().addMark(value_index)
... only applies to the index of the dataset. I thought something like:
mark.setPos(calculate_mark_offset(..),0)
... would slide the mark, but it appears that only affects the label.
Is there a way to access the actual mark line object to move it?
Or a better way to set the value of the mark when using multiple data sets?
I tried to reduce this down to the minimal example case, but if you need more code or clarification let me know. |

Hi Wes,
There are many methods to "highlight" things in ChartDirector. If you would like to use the mark, you can move the mark by adding the mark using a different value.
For example;
#Add a mark at the 4th label position
c.xAxis().addMark(3)
#Add a mark between the 3rd and the 4th label position.
c.xAxis().addMark(2.5)
Note that the mark position does not need to be an integer. It can be a non-integer to specify a position in between the labels.
Hope this can help.
Regards

That is much simpler than what I was trying and I didn't realize float were a possible input.
I calculated the offset based on the dataset count and applied it in setMark(); works as expected!
Thanks! |
