    <p>high guys i store numbers between 1 and 10 in a database and each number is stored with the time it was stored in the database. So i have two sets of data to plot number on the y axis and time on the x axis. however i want to do it in a way so that it plots time in hrs. So say i took 4 numbers in 2 hrs.e.g number 9 at 13:30, 10 at 14:00; 3 at 14:30, 5 at 15:00. plotting the axis is easy but the x axis gives me 2 problems when i want to plot it as a historical event meaning the name of the axis would be hrs and 0 on the axis would be the current time lets say <code>renderer.addTextLabel(0, 15:07);</code> , then 1 on the axis would be the an hour ago or current time minus 60 minuites so <code>renderer.addTextLabel(1, 14:07);</code> and finnaly 2 on the axis would be 2 hrs ago <code>renderer.addTextLabel(2, 13:07);</code>. the two problems i have with my graph is one because current time is a bigger value than the past times when the graph is plotted the x axis starts at 2 and goes down to 0 rather than starting at 0 and going up to two. secondly the graph increments in 100s rather than 60s which represent time. so any values of time than are lets say 13:59 and say 14:00 has a bigger gap between them were the graph assumes there should be values of numbers 13:60 or 13:80 or 13:99 which if we were counting would be true but obviously time goes up to 60 before incrementing the next number. How would i solve this problem? I am new to android and achartengine so please ask me to elaborate if you are unsure. thanks</p>

    1. COI suggest you build a TimeChart rather than a hacked LineChart.

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.
