nplot | Charting library for .NET

So in order to save some time, I wrote a function to plot a graph with a lot of default settings. I want to add a 0 tick to the Axes, so I added Epilog in the plot. However, the 0 does not seem to show up in the graph, and the Epilog does not seem to be working at all.

[See my failed attempt to address this question with ggsave per YBS answer, failed MWE at the very bottom in case anyone knows what I'm doing wrong.] Original question: I would like to download multiple plots with the click of one download button (to prevent an overly-cluttered screen). All plots would go to the download directory, as separate PNG files.

In the below MWE code I have the download button working for the first plot but I haven't been able to figure out how to include the 2nd plot. Without adding a second button!

I'd like the downloaded file to be .PNG (as the below does).

In the full App this MWE is extracted from, there are several more plots and not just the 2 shown in this MWE.

Any thoughts on how to do this?

Here's the MWE code:

I have an app that is creating a dynamic number of images, based on various user inputs. The plotting is being done using renderUI following this link, but with modifications required for my own setup. I now need to export these plots, but can't figure out how to make that happen. I know how to export an individual plot (which is included in the example below), but am looking to modify the code below to be able to export a dynamic number of models.

Would appreciate any suggestions!

I'm trying to use gnuplot from C++ application, gcc version 9.3.0 (Ubuntu 9.3.0-17ubuntu1~20.04). I've encountered strange behavior concerning plotting to files.

So, the reproducible example is:

How would I add the Y axis title "Thousands of People" to cover the entire figure, and not for a single subplot row? The image below shows the y-axis title scrunched at the bottom if the plot. I'm wanting a single y-axis label, oriented in the middle of the overall chart, not the middle of the subplot-row. BONUS: keep the y axis title orientation while allowing the layout(autosize = TRUE).

I have a GUI with multiple tabs, I use tabs 2 and 3. First I coded tab 2 - a figure that takes a plot when a plot data button is pressed, and clears when a clear button is pressed, this worked fine. But when I coded a second tab with similar functionality - yet with a totally different plot - the clear plot/clear fig works on that second tab yet not the first. The clear plot buttons are linked to different clear_fig functions with different names.

I can post the complete code but it's large and I don't want to get kicked off here for adding it, I also don't know how to minimise it into the lowest reproducible error.

Code

Tab2 function

I have been working on a gui to display a graph of values by two indices. That works fine as a standalone py file. I have made a gui that will successfully plot and clear a plot on a frame on canvas. I cannot figure out how to merge the two. The issue is in my plotData function (I have added and commented out a version of it that works very well with a simpler graph). I know my problem is in these lines below because I am using both plt and plot1, but now I don't know anymore what either of them do.

I am making an array of subplots where each item is defined in a for loop. For each subplot, the ylabel is written in LaTeX as the name of a variable (say \theta) with a subindex defined by the counter in the loop. The command .format() written inside the plt.ylabel(r'$\theta_{:2d}$'.format(i)) allows one to specify the index.

However, when the counter has more than 1 digit, the subscript of the variable in the ylabel only applies to the first digit and the remaining ones are written inline. Is there something I am mising in the usage of the .format()? Or is there another way to fix this?

An example:

I would like to add a custom plt.colorbar to a figure containing multiple healpy plots. I have found many posts on how to do this for the usual case of multiple axes objects, but the healpy makes it difficult.

I have the following MWE so far:
