I am building a data analysis app, for viewing data collected by sensors in a formula-like vehicle during the race. I would like to do a line plot (of a sensor reading) and a scatter plot of the logged gps positions during the lap, which is the easy part and I have done it.
However I am struggling on the following: When hovering my mouse over the line plot, I would like the corresponding scatter plot point to change color, because it is easier for me to understand which track section the vehicle is at.
A sample code that represents what have I done is the following:
from bokeh.layouts import gridplot from bokeh.models import ColumnDataSource from bokeh.plotting import figure, show source = ColumnDataSource(data=dict(x=[1, 2, 3, 4, 5], y1=[1, 2, 3, 4, 5], y2=[1, 4, 9, 16, 25])) TOOLS = "box_select,hover,reset" p1 = figure(height=300, width=300, tools=TOOLS) p1.line(x="x", y="y1", hover_color="red", source=source) p2 = figure(height=300, width=300, tools=TOOLS) p2.scatter(x="x", y="y2", size=10, hover_color="red", source=source) show(gridplot([[p1, p2]]))
As you can see I have set
hover_color parameter on both line and scatter plot, but when I hover my mouser over the line plot, the whole line becomes red and so do all the scatter glyphs. If i change my line plot to scatter the code works as expected, however it is not easy to read time series data using scatter plot.
Thanks in advance
