Currently when the table only plots one possible value (e.g., table of
NULL and 1), the cells with a value have no color. I thought this is
counterintuitive, so I tried a custom heatmap using the weather example.
Indeed, using Plotly as below I can get the same heatmap as now, but
when my table only has a single possible value I can still tell the
cells with values from those with no value because they are white.
rendererOptions: {
heatmap: {
colorScaleGenerator: function(values) {
var min, max;
min = Math.min.apply(Math, values);
max = Math.max.apply(Math, values);
return Plotly.d3.scale.linear()
.domain([min, max])
.range(["white", "red"])
;
}
}
},
