Having trouble with an Echart pane using
pyecharts. Specifically, it is remembering a prior state of the plot, and I don’t know how to disable it.
Consider this simple multiline example. I can add new lines to the plot with a widget, but I cannot remove lines from the plot that were added from a previous render.
import numpy as np import panel as pn from pyecharts.charts import Line from pyecharts import options as opts x = np.linspace(0,10,9) y1 = np.cos(x) y2 = np.sin(x) y3 = np.cosh(x) # Much larger y_lim y = [y1, y2, y3] count = pn.widgets.Select(options=[1,2,3], value=1, name='Number of Lines to display') @pn.depends(count) def plot_multiline(count): plot = Line().add_xaxis(xaxis_data=list(x)) for i in range(count): plot.add_yaxis(series_name=str(i+1), y_axis=list(y[i])) return pn.pane.ECharts(plot) pn.Column(count, plot_multiline)
