When working with Julia, it is not uncommon to encounter issues with plotting libraries. One such issue is when plotting with PlotlyJS, the output appears blank. In this article, we will explore three different solutions to this problem.
Solution 1: Updating PlotlyJS
The first solution involves updating the PlotlyJS package to the latest version. This can be done by running the following code:
import Pkg
Pkg.update("PlotlyJS")
After updating the package, try running your code again and check if the plot appears correctly. If not, let’s move on to the next solution.
Solution 2: Clearing the PlotlyJS Cache
Sometimes, the issue can be resolved by clearing the PlotlyJS cache. To do this, follow these steps:
- Close any Julia sessions or notebooks that are currently running.
- Navigate to the directory where your Julia packages are installed. This is typically located at “~/.julia/packages”.
- Find the “PlotlyJS” folder and delete it.
- Restart your Julia session or notebook.
Once you have completed these steps, try running your code again and see if the plot is now visible. If not, let’s move on to the final solution.
Solution 3: Using a Different Plotting Library
If the previous solutions did not work, you can try using a different plotting library instead of PlotlyJS. One popular alternative is the Gadfly package. To use Gadfly, you will need to install it by running the following code:
import Pkg
Pkg.add("Gadfly")
Once Gadfly is installed, you can modify your code to use Gadfly for plotting instead of PlotlyJS. This might require some changes to your existing code, but it can be a viable solution if the other options did not work.
After trying all three solutions, it is difficult to determine which one is the best as it depends on the specific issue you are facing. However, updating PlotlyJS and clearing the cache are good starting points and should be tried first. If those solutions do not work, switching to a different plotting library like Gadfly can be a suitable alternative.
