Intensity Graph <smart-intensity-graph>

IntensityGraph displays a matrix as colour on an x and a y axis, with a colour ramp that says what the colours mean and cursors that read the cell under them: the display a spectrogram, a thermal image, a die map or a sensor array ends in.

Stylesheet

The component is styled by source/styles/default/smart.intensitygraph.css, which is included in smart.industrial-elements.css. It uses the theme's CSS variables and the Industrial tokens (--smart-industrial-*) described in the Themes and Styling guide, so it follows the theme applied to the page.

CSS variables

The component declares 4 CSS variables of its own, on the component itself. Set them in a rule that selects the component, loaded after the component's stylesheet: smart-intensity-graph, or a class or an id on it. A value set on a container does not reach the component, because the component's own declaration replaces the inherited one.

smart-intensity-graph {
    --smart-intensity-height: ...;
    --smart-intensity-plot-background: ...;
    --smart-intensity-grid-color: ...;
    --smart-intensity-axis-color: ...;
}

/* one instance */
#intensityGraph {
    --smart-intensity-height: ...;
}

Themes

Two ISA-101 themes ship with the package: smart.industrial.css and smart.industrial-dark.css. Load one after the base theme and set theme="industrial" or theme="industrial-dark" on the body element. The demo page switches between the three.
