Hi, I have a set of 2-dimensional data, defined over an array of timesteps, but at each timestep the position x-values are different. I’m trying to get contour plots, but the plots come up blank, and each time I get the error message: `Arrays have incorrect length or dimension.`

An example code excerpt goes like:

```
using Plots
tNum = 4; xNum = 3;
FunctionForPlot = Array{Float64,2}(undef, tNum, xNum)
xValsArr = Array{Float64,2}(undef, tNum, xNum)
tValsArr = Array{Float64}(undef, tNum)
for i in 1:tNum
tValsArr[i] = i
for j in 1:xNum
xValsArr[i,j] = i + j^2
FunctionForPlot[i,j] = i*sin(35*j)
end
end
contour([xValsArr[i,j] for i=1:tNum, j=1:xNum],
[tValsArr[i] for i=1:tNum, j=1:xNum],
[FunctionForPlot[i,j] for i=1:tNum, j=1:xNum], fill=true)
```

Any suggestions on how to make this work, or why I’m not getting the plot I expected, would be welcome. Thank you!
