I have a set of data that I'm plotting as a scatter graph which has both positive and negative values on both axis. When I plot this in Flot, the axis are draw at the bottom and the left by default. Is there a way to make it draw the axis through the center of the graph? #X=0 and Y=0?
In other words, instead of this:
I want something like this:
That isn't possible in the default flot. I'm sure it could be hacked in if you wanted to dig into the source, but flot by itself only supports left/right for the y-axis, and top/bottom for the x-axis.
In case anybody else comes across the same need, I created a plugin for Flot and put it here:

It does what I need, but I won't make any promises that it'll fit your particular scenario. If I have time, I might try and update it to cover more scenarios.

I am trying to create one plot with one scatter and multiple lineplots.
For the points to be seen well, I need the scatterplot in the front.
However changing the order inside my code doesn't solve this. The
lineplots always cover the scatterplot. Any ideas?
Please help.
Use the zorder parameter when scatterplotting, e.g.
sns.scatterplot(x, y, ax=ax, color='orange', zorder=7)
You may need to adjust the zorder value depending on the number of elements in your plot.
I've made a chart with Excel 2010's "Combo" option for chart type so I can plot two data series for the same depth points. The image below shows the default, which is very close to what I want - except I would like to have the axes flipped so that the current X axis, which is depth, is displayed as the Y axis and both primary and secondary current Y axes plot as X axes. In other words, I'd like to rotate the chart area by 90 degrees clockwise. The "Switch Row/Column" doesn't do what I want (or expect) and I'm running out of both ideas and patience. Is there an easy fix? Or a hard fix?
Here's the plot as-is:
And here's a dummy plot of the end goal made by rotating the image around in Paint, in case the picture makes it clearer:
Finally, as was pointed out in the comments, the whole thing looks goofy and might be better plotted as a bar graph with two bars. I tried this as well and came away almost all set - but the gray bars plot from left to right and the blue bars plot from right to left. Seems like it should be as simple as changing the "Plot Series On" option to Primary Axis for both, but this destroys the graph.

Suppose one has a plot like this, for which the peak is at (x,y) = (0,0.40). The distribution is plotted in blue. Is it possible to edit the color scheme of the distribution plot in such a way that the color is a gradient - the farther from x (or y or independently for both) the more the color changes - like this?
I've searched SO for help with this, but only found solutions in which line segments were different colors. But, I want the color transition to be smooth (like this but not 3-D) instead of rough, and I want the color to depend on its distance from a particular value rather than pre-determined "randomly". A different SO post did something similar (not quite what I want though), but could only do so as a scatter plot, which only works for changing colors based on x-value if the peak is at x=0 - I'd prefer it be generalized. As an example, the further from x=0 the redder the curve gets. Ideally, there's a way to do this with a matplotlib colormap.
I want to project a 3D plot into a 2D plot. Assuming f(x,y) describes my 3D plot, I want to treat y as a parameter and simultaneously plot f(x,0), f(x,2), f(x,4), etc. in one 2D plot. Instead of going for different line/point styles and colors with a legend in a corner, I'd like to make each plot in the same style and place a label next to each individual line.
Is this even possible in gnuplot or would I have to fall back on something more complex?
I had a similar question recently. There is an option in the development version of gnuplot (4.7.0) that does this. You can change the position of line titles to be at the end/beginning of the line itself. If your plot looks like I imagine (sort of a contour plot) this may be what you want:
plot f(x,y) title 'f(x,y)' at end
Otherwise you may have to specify the labels and their positions manually:
help set label

I'm working on a custom plot on top of which I add a second blank axis object to show a secondary scale on the right hand side of the graph (as well as the primary scale on the left hand side).
Works great (and had been, for years), until I tried it again recently in R2010a and for some reason the primary axis gets its Position property tweaked when the figure is resized or printed, so that it looks OK on the screen at first, but when I print it or resize the figure, the two axes don't line up vertically.
What would do this, and how can I set it up so the two axes maintain the same position?
aha: I think I found it:

Controlling Axes Size
When you create a graph, MATLAB automatically creates an axes to display the graph. The axes is sized to fit in the figure and automatically resizes as you resize the figure. However, MATLAB applies the automatic resize behavior only when the axes Units property is set to normalized (the default).
Note: MATLAB changes only the current axes' properties by default. If your plot has multiple axes, MATLAB will not automatically resize any secondary axes.
You can control the resize behavior of the axes using the following axes properties:
...
ActivePositionProperty — Specifies whether to use the OuterPosition or the Position property as the size to preserve when resizing the figure containing the axes.
