    <p>I noticed that the Xlabels of my Timechart are out of sync with the X- values. The points should be right above the labels. On the left side it OK, but it shifts towards the right. I don't know how to solve this What i get: <a href="http://tinypic.com/r/2uqj905/7" rel="noreferrer">http://tinypic.com/r/2uqj905/7</a> How it should be like: <a href="http://www.achartengine.org/dimages/average_temperature.png" rel="noreferrer">http://www.achartengine.org/dimages/average_temperature.png</a> I tried a line chart or converted the date to a double but that had no effect. Any help would be be nice.</p> <p>regards, Christian</p> <p>This is some of my code:</p> <pre><code> XYMultipleSeriesRenderer renderer = buildRenderer(colors, styles); renderer.setPointSize(5.5f); renderer.setZoomEnabled(false, false); renderer.setMarginsColor(Color.parseColor("#00FF0000")); renderer.setAxisTitleTextSize(16); renderer.setYLabelsAlign(Align.RIGHT); renderer.setLabelsTextSize(15); renderer.setLegendTextSize(15); renderer.setMargins(new int[] { 10, 65, 18, 10 }); int length = renderer.getSeriesRendererCount(); for (int i = 0; i &lt; length; i++) { XYSeriesRenderer seriesRenderer = (XYSeriesRenderer) renderer .getSeriesRendererAt(i); seriesRenderer.setFillPoints(true); seriesRenderer.setLineWidth(4.0f); // dikte van lijn } MinMax minMax = determineMinMax(targetSteps, samples); setChartSettings(renderer, context.getString(R.string.graph_title), dateLabelOnScreenType(type), context.getString(R.string.graph_y_axis), minMax.minX, minMax.maxX, minY, maxY, Color.WHITE, Color.BLACK); renderer.setXLabels(7); renderer.setYLabels(0); renderer.setDisplayChartValues(false); renderer.setShowGrid(true); renderer.setPanEnabled(false, false); // set the data String[] titles = new String[] { context.getString(R.string.graph_legend_target), context.getString(R.string.graph_legend_actual) }; XYMultipleSeriesDataset dataSet = buildDateDataset(titles, xSeriesList, ySeriesList); TimeChart chart = new TimeChart(dataSet, renderer); chart.setDateFormat(dateFormatOnSampleType(type)); GraphicalView gview = new GraphicalView(context, chart); </code></pre>

    1. COSeems like we are missing a large part of the code that could be the problem. Firstly determineMinMax(targetSteps, samples); I don't find this as part of achartengine so I guess it's yours. Are you 100% sure that works as intended? Also I can't see what targetSteps has for value. From your picture there are several odd things, there are 6 dataPoints shown but only 5 labels. Also the start point for the dataPoints are off related to the start point for the labels. I would guess you have some problem with the span not being the same for the labels and the datapoints.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
