    <p>I am plotting a dynamic barchart using flot. I have managed to plot with constant barwidth. Now I want the barwidth to vary based on the output of my analysis. I set <code>var options = { series: { bars:{show:true, barWidth: BarWidth, fillColor: "lightgreen", fill: true }</code> In this code, <code>BarWidth</code> is a javascript variable. My bar starts to plot and gets overlapped when my BarWidth changes. Does anyone has any clue how I can solve my problem? </p> <p>Thank you in advance!</p> <p>@DNS This is my plot function</p> <pre><code>function plot_status(statusData, no_strips) { new_data = new_data.concat([statusData]); var options = { series: { bars:{show:true, barWidth: no_strips*72, fillColor: "lightgreen", fill: true } }, grid: {clickable: true, hoverable: true, borderWidth: 1 } }; $(document).ready(function() { chart1 = $.plot($("#placeholder"), [{ data: new_data, threshold: { below: 0, color: "red" }, color: "black", xaxis: {ticks:8,minTickSize: 1}, yaxis: {min:-1,max:3,tickSize:1}, grid: { borderWidth: 1 } }],options) }); </code></pre> <p>Every four seconds, <code>statusData</code> and <code>no_strips</code> change. new_data contains a series of data that is plotted. The barchar grows with time as long as statusData is concatenated to new_data. <code>no_strips</code> determine the barWidth of each plot of the barchart. I will also include sample of barchart I would like to produce. </p> <p>With a constant <code>barWidth</code> this is what I produce</p> <p><img src="https://i.stack.imgur.com/TO1Ok.png" alt="This is a bar chart with 1200 &lt;code&gt;barWidth&lt;/code&gt;"></p> <p>This is my data: <code>[[0, 1], [1200, 1], [2400, -1], [3600, 1], ... ]; rather I was sending it</code> for my above plot. </p> <p>This is the the data I want to plot [[0, 1], [72, 1], [144, -1], [432, 1],[504,1],...]<code>every</code>[a,b]` is added every four seconds.</p>

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.
