GUI plot panel

The third panel of the PyPLUTO GUI is the plot panel, which allows the user to visualize the loaded data.

At the moment the GUI supports only 1D/2D plots of the PLUTO fluid files. Once the particles will be available in the GUI, the plot panel will be updated to allow the user to plot also the particle data from the very top left window. 3D plots and volume renderings will be added in the future.

Once the variables are loaded and selected, the user can plot the data by clicking on the “Plot” button. The “overplot” checkbox allows the user to plot multiple lines on the same figure in case of 1D plots.

Options: title

The title of the plot can be set by using the “Title” text box.

Options: aspect ratio

The “Auto-ratio” checkbox allows the user to set the aspect ratio of the plot automatically. If the checkbox is unchecked, the aspect ratio will be set to “equal”, meaning that the x- and y-axes will have the same scale. The default value is “Auto-ratio”, which means that the aspect ratio will be set automatically based on the data.

Options: range

The (x/y/v) range text boxes allow the user to set the range of the plot. The user can set the range by typing the desired values in the text boxes. In case of 1D plots, the user can set the range of the x-axis and the y-axis. In case of 2D plots, the user can set the range of the x-axis, the y-axis, and the variable to be plotted (v-axis). The range can also be set automatically by simply leaving these text boxes empty. The default value is “Auto”, which means that the range will be set automatically based on the data.

Options: scales

The x- and y-scales can be set by using the “x-scale” and “y-scale” combo boxes. Possible options are “linear”, “logarithmic”, “symlog” and “asinh”. The default value is “linear”, which means that the x- and y-axes will be plotted on a linear scale. The last two options require an additional threshold value to be set in the “tresh” text box. The 2D plot scale can be set by using the “v-scale” combo box. Possible options are “linear”, “logarithmic”, “symlog”, “2slope”, “power” and “asinh”. The default value is “linear”, which means that the variable will be plotted on a linear scale. Some scales trequire an additional threshold value to be set in the “tresh” text box.

Options: colormap

The colormap can be set by using the “Colormap” combo box. The user can choose from a list of available colormaps. The default value is “plasma” which is a perceptually uniform colormap. The user can also select the colormap type by using the leftmost panel in the cmap section. Then the user can choose the designed colormap from the middle combo box. The colormap can also be reversed by checking the “Reverse” checkbox.

Options: update plot

The “Update plot” button allows the user to update the plot without having to reload the data. This is useful when the user wants to change the plot settings or the colormap without having to reload the data. The user can also change the title, range and scales without having to reload the data. The plot will be updated automatically when the user clicks on the “Update plot” button.

Options: clear plot section

The “Clear” button will simply clear the plot panel, allowing the user to start over with a new plot. This is useful when the user wants to plot a new variable without having to reset all the panels.

Options: reload canvas

The “Reload canvas” button allows the user to quickly change the plot settings by reloading the canvas. This is useful when the user has made changes to the plot settings or when the user wants to quickly switch between different plot settings without having to close and reopen the GUI.
