Minor feature request: the plot toggle button appears as 1, not ①, both in Chrome and Firefox. This would make the behavior consistent with other terminals, such as qt. Some environments, such as interactive notebooks (like Jupyter), which is my use case for the canvas terminal, are narrow, and placing the mousebox on the bottom would allow the plot itself to be wider and thus easier to read.įeature request: make the # button always active, even if no set grid command has been issued. These are my conclusions and feature requests:ĭocumentation: The mousebox appears to the left of the plot, not the bottom, as stated in the documentation.ĭocumentation: State that the # button is only active if set grid has been issued.įeature request: add a configuration option to the canvas terminal to place the mousebox at the bottom. I can toggle the plots now I don't know what I was doing wrong before. I have had a chance to run more tests, both in Firefox and in Chromium. It would make a great relatively self-contained project for someone who is interested in contributing to gnuplot.Įthan, thank you for your reply.
#GNUPLOT GRID DRIVER#
Gnuplot's canvas driver should be extended or rewritten from scratch to take advantage. Since then of course the standard and browsers that implement have added lots of features, not least of which is letting the browser render the text. It was written back when HTML5 was still being developed, and was at the time limited by lack of support in the standard for such things as text rendering (D'oh!). There are a lot of things that could be improved for the canvas terminal. There probably should be some option to say "add a grid but start with it toggled off", but there isn't. Step 1 In gnuplot, comments are designated with the sign.
#GNUPLOT GRID SOFTWARE#
The software we're going to use is gnuplot. So add a "set grid" to your commands and it should work. The X-axis of the plot is column 1 and the Y-axes are all the other columns. Did you try turning on the debugging dashboard in your browser? It might show error messages or let you trace the mouse events.Ģ) The grid widget can only toggle a grid if there is one in the plot. I did nothing special, so I don't have any suggestions as to what might not be working for you. That includes pretty much everything in a 2D plot but only some variants of graphs created with splot.ġ) For me your simple example does produce an html file containing a plot that can be toggled by clicking on the ① symbol (tested with Chrome). So the ① button can only toggle a "plot 1" if it is there and is the sort of plot that can be toggled. The toggles can only toggle things that are actually in the plot. The following plot is displayed when the Fortran program is executed.I will try to find time to respond at more length later, perhaps after moving this to Feature Requests. gnuplot is then called to run a file named data_t which is located in the same folder as the Fortran program. The above Fortran program actually calculates the points on the parabola y=x^2 and then writes into the file data.
Once gnuplot finishes plotting (to your display/ or to a file), then the control will be given back to the Fortran program to continue execution. So what has it got to do with Fortran programs? Since gnuplot can be run from a terminal, we can ask the Fortran program to open a system terminal and ask to run gnuplot. It is a command line plotting utility that can produce publication-quality plots. Then I came across the wonderful gnuplot software (free and open source !!). How great would it be if we can have a plotting option directly in Fortran programs? I was having trouble finding a proper way to do this.
