Is there a way to adjust fontsize of labels in plots thru jslink?

based on the topic you linked you can di this:
cmaps = matplotlib.pyplot.colormaps()
cmap_dict = {}
for cmap in cmaps:
_cmap = matplotlib.cm.get_cmap(str(cmap), 12)
cmap_dict[str(cmap)] = [matplotlib.colors.rgb2hex(_cmap(i)[:3]) for i in range(_cmap.N)]
def get_blank_plot():
#p1 = hv.Curve([],kdims=["Date"],vdims=["Price [BTC]"]).opts(responsive=True)
ls = np.linspace(0, 10, 200)
xx, yy = np.meshgrid(ls, ls)
p1 = hv.Image(np.sin(xx)*np.cos(yy),kdims=['x','y'],vdims=['z'])
return p1
class Example(param.Parameterized):
EXAMPLE_PLOT = get_blank_plot().opts(width=500,height=400)
def __init__(self, **params):
super().__init__(**params)
self.plot_pane = pn.pane.HoloViews(self.EXAMPLE_PLOT)
self.font_size = pn.widgets.IntInput(end=40,start=5,value=13,name='Font size')
self.font_size.jslink(self.plot_pane, code={'value':'''
xaxis.major_label_text_font_size = `${cb_obj.value-2}px`
xaxis.axis_label_text_font_size = `${cb_obj.value}px`
yaxis.major_label_text_font_size = `${cb_obj.value-2}px`
yaxis.axis_label_text_font_size = `${cb_obj.value}px`
'''})
def panel(self):
return pn.Column(self.font_size, self.plot_pane)
app = Example(name='')
app.panel()
Thanks! This is super useful. Maybe panel can have a util dropdown method for post-tweaking to modify all these settings (colorbar + axis range + fontsize)
Yes I think it is a good idea to produce better plots live for presentation for exemple.
I search to make this class automatically but did it by hand at the end…
And I forget to mention that are is a nice exemple for bokeh !
