AChartEngine is a charting library for Android applications. It currently supports the following chart types: line chart area chart scatter chart time chart bar chart pie chart bubble chart doughnut chart range (high-low) bar chart dial chart / gauge combined (any combination of line, cubic line, scatter, bar, range bar, bubble) chart cubic line chart All the above supported chart types can contain multiple series, can be displayed with the X axis horizontally (default) or vertically and support many other custom features. The charts can be built as a view that can be added to a view group or as an intent, such as it can be used to start an activity. The model and the graphing code is well optimized such as it can handle and display huge number of values. AChartEngine is currently at the 1.0.0 release. New chart types will be added in the following releases. Please keep sending your feedback such as we can continually improve this library.

TimeSeries with multiple scales #343

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
Please make it possible to use TimeSeries with multiple scales. Mixing 
TimeSeries on scale 1 and an XYSeries on scale 2 is cumbersome if the XYSeries 
does not contain all the data points.

What version of the product binary library are you using?
1.1.0

I am trying to show multiple lines and a series of bars in a combined XY chart 
view used for financial data, the chart has 2 y-scales.

use this class, works good for me:

import java.util.Date;

/**
 * A series for the date / time charts.
 */
public class MyTimeSeries extends org.achartengine.model.XYSeries {

    /**
     * Builds a new date / time series.
     *
     * @param title the series title
     */
    public MyTimeSeries(String title) {
        super(title);
    }

    /**
     * Builds a new date / time series.
     *
     * @param title the series title
     */
    public MyTimeSeries(String title, int scaleNumber) {
        super(title, scaleNumber);
    }

    /**
     * Adds a new value to the series.
     *
     * @param x the date / time value for the X axis
     * @param y the value for the Y axis
     */
    public synchronized void add(Date x, double y) {
        super.add(x.getTime(), y);
    }

    protected double getPadding(double x) {
        return 1;
    }
}
