Bonjour a tous

j'ai concu un graphique avec de nombreuses courbes ( graph de bourse ).
je souhaite ajouter une ligne sur le graphique a la souris . un cercle ou un texte ..

Merci.

Hello,

Deja avec la librairie c'est impossible, car comme beaucoup elle travaille du cote serveur et non client, donc pour pouvoir tracer et ajouter des lignes a la souris, il te faut pouvoir recuperer les infos des points que tu souhaites grace a quelque chose, et ce quelque est a mon avis le javascript.

Voila

Hello .. bon ami français

( English at the end )

je ne suis pas en architecture client serveur ..

je suis en train de concevoir une application stand alone ..
j'ai les infos sur les points .. etc ..

je crois qu'il faut que je regarde la gestion de la souris dans jgraph et les listener souris ... :+((

j'ai vu l'application de zoom, je pense qu'il faut que je m'inspire ..
Il me faut du temps ... pour comprendre tout ca ..

Sinon, je limite l'affichage de ma courbe à 3 mois .. ( plage visible) sur 2 ans. J'ai un probleme avec les axes y .. et la plage de visibilité ( voir Jscrollbar )..

je cherche des sources dans ces deux domaines .. et je partage aussi des sources ..

@++

Sorry , for my poor english .. i try too translate..

I work with a stand alone application with jfreegraph.
I have two main problems ..

First , add a line beetween two points with mouse. ( after creation of the chat, maybe like the mouse zoom example )

Second, I add the jscrollbar in my application. The main problem is the visibility of the values in the Y axis ( not domain ).
My visibles values are include in 12 to 14 and the application display the range of all values ( 4 to 50 ). How to restrict the display to visible values ?? )..

Thanks bye*

I got the same question.

So I would really appreciate if you would share here the solution that you might have found to that question.

Thanks.

I read your request.

You need to change some features in my source..
the creation of the TimesSeries .. and the Main().

My source is base in the mousezoom demo found in the jfreechart demo directory and i adapt it to my software.

I found two other way to do a program ..

Search " ChartScrollBar " .java in the forum ..
and
"PanScrollZoomDemo" .java in the forum


the source ..
