Bug: savefig(p, "html") results in error ReferenceError: Can't find variable: plots_jl_plotly_init #503
Description
Describe the bug
Hi there,
With the current version, savefig does not produce a running HTML file. Here is a MWE:
cd(expanduser("~/Desktop"))
run(`rm -rf Project.toml Manifest.toml`)
using Pkg
Pkg.activate(".")
Pkg.add("Plots")
Pkg.add("PlotlyJS")
using Plots
plotlyjs()
p = plot(randn(10))
savefig(p, "test.html")
The resulting HTML has the following form:
<script src="https://cdn.plot.ly/plotly-2.6.3.min.js"></script> <div id="4c1c9687-32be-43b7-91a4-9d678663744e" style="width:600px;height:400px;"></div>
<script src="https://requirejs.org/docs/release/2.3.7/minified/require.js" onload="plots_jl_plotly_init()"></script>
<script>
function plots_jl_plotly_init() {
Plotly.newPlot('4c1c9687-32be-43b7-91a4-9d678663744e', [
...
</script>
The Web Inspector in Safari throws the error ReferenceError: Can't find variable: plots_jl_plotly_init – and the html also does not work in Firefox. In order to get the figure to work, one has to swap the 2nd and the 3rd <script> statement:
<script src="https://cdn.plot.ly/plotly-2.6.3.min.js"></script> <div id="4c1c9687-32be-43b7-91a4-9d678663744e" style="width:600px;height:400px;"></div>
<script>
function plots_jl_plotly_init() {
Plotly.newPlot('4c1c9687-32be-43b7-91a4-9d678663744e', [
...
</script>
<script src="https://requirejs.org/docs/release/2.3.7/minified/require.js" onload="plots_jl_plotly_init()"></script>
With this modification, plots_jl_plotly_init() is defined before it is loaded.
