我已经使用 jpgraph 创建了一个图表——它可以工作,但是由于我的 x 轴上标签的长度,一些文本被“截断”并且不可见。我创建了一个自定义函数来使用换行符,但即使这样,它仍然会修剪图表上一个标签上的几个字符。
有没有一种方法可以实际定义 x 轴标签的实际长度,例如以像素为单位设置宽度?谢谢
// Create the graph. These two calls are always required
$graph = new Graph(1000,500,'auto');
$graph->SetScale("textlin");
//$theme_class="DefaultTheme";
//$graph->SetTheme(new $theme_class());
// set major and minor tick positions manually
$graph->yaxis->SetTickPositions(array(0,1,2,3,4,5), array(0.5,1.5,2.5,3.5,4.5));
$graph->SetBox(false);
//$graph->ygrid->SetColor('gray');
$graph->ygrid->SetFill(false);
$graph->xaxis->SetLabelAngle(90); // 45 degrees angle
$graph->xaxis->SetTickLabels($new_labels);
$graph->yaxis->HideLine(false);
$graph->yaxis->HideTicks(false,false);
// Create the bar plots
$b1plot = new BarPlot($data);
// ...and add it to the graPH
$graph->Add($b1plot);
$b1plot->SetColor("white");
$b1plot->SetFillGradient("#4B0082","white",GRAD_LEFT_REFLECTION);
$b1plot->SetWidth(45);
$graph->title->Set("Bar Gradient(Left reflection)");
// Display the graph
$graph->Stroke();
