ChartCanvasAxis.log2lin

Syntax

log2lin(value: Number);

Parameters

value. Logarithmic value of the chart axis.

Description

The log2lin method converts log value of the chart axis to linear value.

Comments

The method returns value of the Number type.

Example

Executing the example requires that the HTML page contains the Chart component named chart (see Example of Creating a Scatter Chart). Determine linear and logarithmic values corresponding to the chart axis coordinate equal to 100:

// Get Y axis on the chart
var yAxis = chart.getYAxis();
// Get axis value corresponding to the coordinate 100
var coord = 100;
var axisValue = yAxis.getAxisValue(coord, true);
console.log("Coordinate %s on the chart axis corresponds to the following values: ", coord);
var logValue =  yAxis.lin2log(axisValue);
console.log("- on the logarithmic axis: %s,", logValue);
var linValue = yAxis.log2lin(logValue);
console.log("- on the linear axis: %s", linValue);

After executing the example the browser console shows linear and log values corresponding to the coordinate 100:

Coordinate 100 on the chart axis corresponds to the following values:

- on the logarithmic axis: 1.3774404986134837e+49,

- on the linear axis: 49.139072847682115
