title: Zoom in and zoom out for R graph
body: <p>I know the question was already asked, but i couldn't solve my problem.
  I get a graph unreadale when i choose the text argument for my graph and when i choose the identify argument it's not better.<img src="https://i.stack.imgur.com/FGdCM.png" alt="enter image description here"></p>
  
  <p>This is what i get whith this script :</p>
  
  <pre><code>VehiculeFunction &lt;- function(data, gamme, absciss, ordinate, label, xlim, ylim){
    my.data &lt;- data[data$GAMME == gamme,]
    ma.col = rgb(red = 0.1,blue = 1,green = 0.1, alpha = 0.2)
    X &lt;- my.data[[absciss]] 
    Y &lt;- my.data[[ordinate]] 
    Z &lt;- my.data[[label]]
    X11()
    plot(X, Y, pch=20, las = 1, col = ma.col, xlab = absciss, ylab = ordinate, xlim = xlim, ylim = ylim)
    text(X, Y, labels = Z, pos=3, cex = 0.7, col = ma.col)
    #identify(X, Y, labels = Z, cex = 0.7)
  }
  
  VehiculeFunction(data.vehicule, "I", "GMF.24", "Cout.24", "NITG", c(0,0.2), c(0,0.2)) 
  </code></pre>
  
  <p>I used iplot, but i couldn't add the identify and text argument...
  I never used ggplot, so i don't know if it's could solve my problem.</p>
  
  <p>Thank you for help.</p>
