How to change colors in "plot_array"?

[wsc1008-cugb]

When I change the color in plot_array(),the result of corresponding color is not generated. The result shows that only the edge color was changed, instead of the facecolor.

Hi @wsc1008-cugb, when plotting arrays, the color at any point is a function of the array's value there. This is achieved with colormaps. You can use cmap to override the default colormap, which is viridis. For example:

mx = flopy.plot.PlotCrossSection(ax=ax, model=swt, link={'row': 0})
conduct1 = mx.plot_array(hk11, masked_values=[hk2, hk3], cmap="plasma", alpha=0.75)

You'll probably want a sequential colormap for a smooth gradient.

Thank you a lot, it works!
