I have a three column data; I want to plot a scatterplot with the first two columns and colormap the data along the third axis. How can this be done using any of the plotting modules available with python ?

I have two data series with dates that do not overlap. How do I plot them separately using different colours under the same graph and date axis?
Thanks
I have a shapefile from GADM that has a lot of polygons showing the states and provinces of Colombia, but I'm only interested in one of them. Is it possible to extract this one polygon and plot it afterwards using python3?
I'm plotting a column of data which represents a time series in gnuplot. Every value represents a time value after 500 iterations / time units. Can I tell gnuplot to multiply the x-values it displays by 500?
I thought this would be a standard problem since every time one has to plot a time series one needs to tell the plotting program what time unit each iteration has.
I don't want to create an extra column with x-values manually, since I have a lot of different data of different length. I don't want to create a x column for everyone of them.
If you have only a single column, gnuplot uses the row number as x value. This can be accessed by the pseudo column 0 and scaled like
plot 'datafile' using ($0*500):1
or equivalently, if you're calling this from a shell script
plot 'datafile' using (column(0)*500):1
I would like to visualize a 3D scalar field as given by a dataset which has the following format:
x y z f(x,y,z)
That is, my dataset consists of four columns where the first three columns denote a position and the fourth column the value of the scalar field at that position.
Is there a fast and easy way of generating a contour plot from such a dataset? I have been looking into gnuplot, but I have not been able to figure out how to create a simple contour plot from my dataset, though it looks to me it should be possible.
Gnuplot can handle only 3D-data, i.e. x, y, f(x, y). A fourth dimension can be applied only in form of a color information.
I want to make a scatter graph of the output of ftrace (from kernel) on asm_do_IRQ..The problem is there are 8000+ entries and I get the results as a single line plot. Is there any way to do a normalisation of the values so that I can get a scatter plot? The values I want to print are as below:
Interrupt Time
uart-pl011 196.98111
Nomadi 196.983246
prcmu 196.983307
dma40 196.983429
dma40 196.984222
Nomadi 196.98642
dma40 196.988922
prcmu 196.988953
since the number of values are huge, excel takes time on the Y axis and plots the number of interrupts on the X axis. But i want the interrupts by name on the Y axis and time on the X axis.
looks like this is not possible. Scatter graphs can only be used to plot two variables, and since one of the axes i want to plot is a string, this is not possible - i can only get a trend, not the exact plots vs time
