I would like to add a % tag to the z value that is show on hover. Also, right now, my colorscale is only displaying -10 to 10, but I would like it to show % so -10% to 10%. Here is the code I have. I have tried to add the ticksuffix : “%”, but I’m not sure where I should put it since it seems like the colorscale is not an axis like the x and y axis.
var xValues = ['A', 'B', 'C',];
var yValues = ['W', 'X', 'Y', 'Z'];
var zValues = [[-2.45,-0.4,1.3],
[2.9,3.9,-5.66],
[0.5,-2.6,-3.2],
[-8.3,-0.5,-0.1]];
var a_text = [["Comodities + producers","Consumer Discretionary","Utilities Equities"],
["Health and Biotech","Global Real Estate","Financial Equities"],
["Emerging Market Bonds","Technology Equities","Industrials Equities"],
["Oil and Gas","China Equities","Diversified Portfolio"]];
var data = [{
x: xValues,
y: yValues,
z: zValues,
hoverinfo: "z",
reversescale: true,
type: 'heatmap',
// zsmooth: "best",
colorscale: "Spectral",
zauto: false,
zmin:-10,
zmax:10,
showscale: true,
}];
var layout = {
title: 'Annotated Heatmap',
annotations: [],
xaxis: {
ticks: '',
side: 'top',
tickfont: {color: 'rgb(255,255,255)'}
},
yaxis: {
ticks: '',
ticksuffix: ' ',
width: 700,
height: 700,
autosize: true,
tickfont: {color: 'rgb(255,255,255)'},
}
};
for ( var i = 0; i < yValues.length; i++ ) {
for ( var j = 0; j < xValues.length; j++ ) {
var currentValue = (zValues[i][j]);
if (currentValue < -0.05) {
var textColor = 'white';
}else{
var textColor = 'black';
}
var result = {
xref: 'x1',
yref: 'y1',
x: xValues[j],
y: yValues[i],
text: a_text[i][j],
font: {
family: 'Arial',
size: 12,
color: 'rgb(50, 171, 96)'
},
showarrow: false,
font: {
color: textColor
}
};
layout.annotations.push(result);
}
}
Plotly.newPlot('myDiv', data, layout);
