    <p>i have this piece of code. To explain: </p> <p>The user inputs "initcores" data and "ttime" data (the "fcores" is a result). </p> <p>I want to fill the x array with values from 0 to ttime and the y from initcores to fcores and do the scatter plot ,x vs y. </p> <p>I have one problem :</p> <blockquote> <blockquote> <p>If i put " for (double t=0;t&lt;=fcores;t=t+fcores/10.0){ y.add(t); " </p> <p>it gives me a plot but its wrong. </p> <p>if i put " for (double t=initcores ;t&lt;=fcores;..." (which is right because we are starting from initcores) </p> <p>it doesn't appear anything in the plot. </p> </blockquote> </blockquote> <p>Am i not doing sth right here? </p> <p>Thank you!</p> <pre><code> ......... Double initcores= getInitcores(); Double fcores= getFcores(); Double ttime=getTime(); ArrayList&lt;Double&gt; x =new ArrayList&lt;Double&gt;(); ArrayList&lt;Double&gt; y =new ArrayList&lt;Double&gt;(); //fill x,y values for (double t=0;t&lt;=ttime;t+=ttime/10.0){ x.add(t); } for (double t=initcores;t&lt;=fcores;t+=fcores/10.0){ y.add(t); } TimeSeries series = new TimeSeries("Number of cores"); for (int i=0;i&lt;x.size();i++){ for (int j=0;j&lt;y.size();j++){ series.add(i,j); } } .......... </code></pre> <p>--------------EDIT --------------------------------------</p> <p>If i use :</p> <pre><code>double [] x = {0.0,ttime}; //time axis double [] y = {initcores,fcores}; //number of cores axis TimeSeries series = new TimeSeries("Number of cores"); for (int i=0;i&lt;x.length;i++){ series.add(x[i],y[i]); } </code></pre> <p>it gives me a plot with only 2 points.That's why i am trying to fill the points between them (for x axis :0-ttime ,for y axis:initcores-fcores).</p>

    2. COAs i say i am expecting a lot of points ,for example from 0 - ttime.I The user gives only ttime,initcores.The result is fcores.I am trying to fill the points between 0-ttime an initcores-fcores.But i get an empty plot.If instead of " for (double t=initcores;t<=fcores.." put "for (double=0..)" ,then i get a plot but it's totally wrong.

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.
