How to sort columns after col_split

[stephanmg]

Hi,

I have a col_split by a pd.Series to group into 3 different groups A, B, and C.

The groups A, B, C seem to be automatically sorted ascending.

However I need to sort with a custom order within the groups A, B, C. How is this possible?

Hi @stephanmg ,

Take a look at:
https://dingwb.github.io/PyComplexHeatmap/build/html/notebooks/advanced_usage.html#Cluster-between-groups-and-cluster-within-groups

I guess col_split_order is what you are looking for.

[stephanmg]

Yes, I forgot that I need to also specify col_cluster=False, col_dendrogram=False is not enough.

[stephanmg]

@DingWB thank you! Is it also possible to remove or reposition the label of a anno_barplot(...)?

Code:
AB=anno_barplot(....

I need to move the label AB or remove it in the plot.

Remove label with label_kws: 'visible': False. Can I also move the label more away from the plot?

Also, how can i provide a label to anno_barplot which contains spaces, in the examples in the docs there are never spaces I think, is this perhaps not supported? I need to write AB variant=anno_barplot(...) in essence.

[DingWB]

How did you control the pad in a normal barplot?
You can control the pad similarly by taking the ax of the anno_barplot and doing whatever you want.

[stephanmg]

Thanks, what about the label name? Can I somehow include spaces?

[DingWB]

Please try.

[stephanmg]

No, sorry, I mean in the labels name. This is a second question, on how to rename the label, e.g. AB for the annotation to AB variant`

[DingWB]

See this docu: https://dingwb.github.io/PyComplexHeatmap/build/html/notebooks/advanced_usage.html#Add-multiple-heatmap-annotations-using-for-loop

You could prepare a dict and pass it to HeatmapAnnotation. You can give whatever key to the dict (including space).

legend_kws with label I assume? doesn't work somehow for my anno_barplot. :/

[stephanmg]

row_ha = HeatmapAnnotation(ABadvanced=anno_barplot(histo_data_for_row_ha, colors=bar_color, height=15), verbose=0, label_kws={'label': "# problems solved", 'rotation':0, 'fontsize': 8, 'horizontalignment':'left','verticalalignment':'bottom', 'visible':False}, axis=1)

[stephanmg]

But this will not rename Abadvanced to "# problems solved"... don't know why. Could you help out again? Thanks!

@DingWB 建议对列名进行分组的时候加上 sort=False的参数保持默认的输入顺序

        col_clusters = self.col_split.groupby(cols,sort=False).apply(
            lambda x: x.index.tolist()
        )
