Make a table and a colored image of 1x1 pixel. Then display that image with the size you need.

Example:

<table cellspacing=1 cellpadding=0>
<tr valign=bottom bgcolor=#ffffcc>
<td><img src=dot_red.gif width=12 height=120></td>
<td><img src=dot_red.gif width=12 height=71></td>
<td><img src=dot_red.gif width=12 height=81></td>
<td><img src=dot_red.gif width=12 height=114></td>
<td><img src=dot_red.gif width=12 height=150></td>
<td><img src=dot_red.gif width=12 height=136></td>
<td><img src=dot_red.gif width=12 height=119></td>
<td><img src=dot_red.gif width=12 height=134></td>
<td><img src=dot_red.gif width=12 height=67></td>
<td><img src=dot_red.gif width=12 height=66></td>
<td><img src=dot_red.gif width=12 height=109></td>
</tr>
</table>

Perhaps a version 4 solution:

<table cellspacing=1 cellpadding=0 WIDTH=200>
<tr><td>-</td><td>-</td><td>-</td><td>-</td><td>+</td><td>-</td><td>-</td><td>-</td><td>-</td><td>1</td><td>-</td><td>-</td><td>-</td><td>-</td><td>+</td><td>-</td><td>-</td><td>-</td><td>-</td><td>2</td></tr>
<tr><td BGCOLOR="RED" COLSPAN=12>1 </td><td BGCOLOR="WHITE" COLSPAN=8>12</td></tr>
<tr><td BGCOLOR="RED" COLSPAN=2>2  </td><td BGCOLOR="WHITE" COLSPAN=18>2</td></tr>
<tr><td BGCOLOR="RED" COLSPAN=3>3  </td><td BGCOLOR="WHITE" COLSPAN=17>3</td></tr>
<tr><td BGCOLOR="RED" COLSPAN=4>4  </td><td BGCOLOR="WHITE" COLSPAN=16>4</td></tr>
<tr><td BGCOLOR="RED" COLSPAN=14>5 </td><td BGCOLOR="WHITE" COLSPAN=6>14</td></tr>
</table>

Watch out for the user's browser having "proportional" fonts;
all your attempts to "draw" using "fixed-pitch" text-characters
will not align.
how about making the crart in windows/access/excel andi nporting it into the HTML page
Why not:

<p> I am kessy
</p>

<hr size="10"> (size you can moderate your own)
I just created a bar.
(Then you get a line, bar, or:)
hr color="#0000FF" size="10">
Then your bar is colored without using a picture.

All of you don't understand my question.
I want to create a chart (same the chart in Excel). If using image files, size of them is too big. Is there any way to draw that chart by modify some data ( some numbers).
You can program in Java or Applet.

Commented:
Why is it "too big" ??
Modems are getting faster, and LAN-connections are fast,
so downloading an image should be no problem.
Disk-space is getting cheaper, so storing the image
should be no problem, either.

Commented:
What do you mean "too big"
i suggested you use a 1x1 pixel image, you can hardly call that big.

But if you want to use Java, you can, there are a lot of applets around which show graphs based on numbers you put in parameters.

One comes with the JDK 1.02, it's called chart.class, see http://www.whatrain.com/javatest/sun/barchart/chart.html

I have found it very quickly on the wen by search for "chart.class" +applet.

A search for "barchart.class" or whatever you think people might call such an applet will give you numerous webpages, and sure some of them will comtain what you want.

Hmm, if none understands your question, then maybe you should try and rephrase it.
