[英]plotly heatmap in R - change scale title
I've created a heat map in R using plot_ly
, but I can't for the life of me figure out how to change the name that appears above the colour legend (short of changing the name of the input dataframe). 我使用
plot_ly
在R中创建了一个热图,但我不能为我的生活找出如何更改颜色图例上方显示的名称(更改输入数据框的名称)。
Trouble is, I'd like spaces in the name of the title, which passing as the data to the plotly
call makes difficult. 麻烦的是,我想要标题名称中的空格,因为数据传递给
plotly
调用变得困难。
There MUST be a way to edit it directly as there is for every other label/title surely?! 必须有一种方法来直接编辑它,因为肯定会有其他标签/标题吗?!
I was hoping it would inherit from legend=
but seemingly no.. Code and output image below (trying to change the bit that currently says "data.matrix, adjwallace"). 我希望它会继承
legend=
但看似没有..下面的代码和输出图像(试图改变当前说“data.matrix,adjwallace”的位)。
(I havent provided the data, since it isn't relevant to the particular problem I don't think - and I had to mess with it's format, but I can edit if necessary). (我没有提供数据,因为它与我不认为的特定问题无关 - 我不得不弄乱它的格式,但我可以根据需要进行编辑)。
fonts <- list(
family = "sans-serif",
size = 12
)
x.axisSettings <- list(
title = "",
zeroline = FALSE,
showline = FALSE,
showticklabels = TRUE,
showgrid = FALSE,
)
y.axisSettings <- list(
title = "",
zeroline = FALSE,
showline = FALSE,
showticklabels = TRUE,
showgrid = FALSE,
)
legend.Settings <- list(
font = fonts,
title = "Adjusted Wallace Coefficients"
)
plot_ly(z = data.matrix(adjwallace),
colorscale= "Hot",
name = "Adjusted Wallace Coefficients",
x = names(adjwallace),
y = names(adjwallace),
type = "heatmap") %>%
layout(xaxis=x.axisSettings,
yaxis=y.axisSettings,
legend=legend.Settings)
