Putting two different entries under same label in a legend

I have plotted a graph with different data sets and trend lines. I was wondering if it was possible to have two different entries under the same label without the label appearing twice in the legend:

ax.plot(JD_inc, mag_inc, 'x', label = "Increasing Magnitude")
ax.plot(JD_dec, mag_dec, 'x', color = "forestgreen", label = "Decreasing Magnitude")

ax.plot(new_x_inc, new_y_inc, color = "orange", label = "Increasing Magnitude")
ax.plot(new_x_dec, new_y_dec, color = "crimson", label = "Decreasing Magnitude")


ax.errorbar(our_jul_day, our_mag, yerr = our_err, fmt = "x", color = "black", zorder = 10, label = "Our Data")

plt.legend()

is it also possible to remove the error bar from the "our data" label?

Here is an image of my current graph:

So, for example, is it possible to get the orange line and the blue point to essentially over lap in the legend?

Based on the HandlerTuple example given in this link, the following should work in your case:

jd_inc_data, = ax.plot(JD_inc, mag_inc, 'x', label = "Increasing Magnitude")
new_x_inc_data, = ax.plot(new_x_inc, new_y_inc, color = "orange", label = "Increasing Magnitude")

plt.legend([(jd_inc_data, new_x_inc_data)], ["Increasing Magnitude"])
