Hi David, To display more than one chart on a page, you must follow these constraints:
- Only load the loader once. - Only call google.charts.load one time. Merge all the packages you need for all the charts into one array. - You can call google.charts.setOnLoadCallback more than one time, but use a unique function name for each function you declare. Don't call them all 'drawChart'. - Use a unique id for each chart. Don't call them all 'chart_div'. 2016-01-19 6:30 GMT-05:00 David Segarra <[email protected]>: > Hola, > > estoy desarrollando un proyecto web en jsp y necesito mostrar varias > gráficas con Google Charts pero cuando introduzco el codigo necesario solo > me muestra la primera que aparece en la página. > > El código es el siguiente: > > <table> > <tr> > <th id="columna_centro">Evolución ventas > <%=request.getParameter("ano1") %> vs. <%=request.getParameter("ano2") > %></th> > </tr> > <tr> > <td><div id="chart_div_evolucion" > style="margin-left: 30px;"></div></td> > </tr> > </table> > <br> > > <script type="text/javascript" src=" > https://www.gstatic.com/charts/loader.js";></script> > <script type="text/javascript"> > google.charts.load('current', {packages: > ['corechart', 'bar'], 'language': 'es'}); > google.charts.setOnLoadCallback(drawChart); > > function drawChart() { > var data = > google.visualization.arrayToDataTable([ > ['Year', "" + > <%=request.getParameter("ano1") %> +"", "" + > <%=request.getParameter("ano2") %> +""], > [<%=data%>] > ]); > > var options = { > legend: { position: 'bottom' }, > vAxis: { > format: 'currency' > }, > colors: ['#BDBDBD', '#E6E6E6'], > height: 400, > width: 700 > }; > > var chart = new > google.visualization.LineChart(document.getElementById('chart_div_evolucion')); > > chart.draw(data, options); > } > > </script> > > <table> > <tr> > <th id="columna_centro">Ventas acumuladas > <%=request.getParameter("ano1") %> vs. <%=request.getParameter("ano2") > %><br> (Hasta mes actual)</th> > <th id="columna_centro">Ventas proyectadas > <%=request.getParameter("ano1") %> vs. <%=request.getParameter("ano2") > %></th> > </tr> > <tr> > <%if(porcentajeAcumulado < 0){ %> > <td style="color: > red"><%=Math.round(porcentajeAcumulado) %>%</td> > <%}else{ %> > <td><%=Math.round(porcentajeAcumulado) %>%</td> > <%} %> > <%if(porcentajeProyectado < 0){ %> > <td style="color: > red"><%=Math.round(porcentajeProyectado) %>%</td> > <%}else{ %> > <td><%=Math.round(porcentajeProyectado) > %>%</td> > <%} %> > </tr> > <tr> > <td> > <div id="chart_div_acumulada" style="width: > 450px; height: 400px; padding-left: 50px;"></div> > <script type="text/javascript"> > google.charts.load('current', {packages: > ['corechart', 'bar'], 'language': 'es'}); > google.charts.setOnLoadCallback(drawChart); > function drawChart() { > var data = > google.visualization.arrayToDataTable([ > ["", "", { role: "style" }], > [""+<%=request.getParameter("ano1") %>, > <%=ventaAcumulada1%>, '#BDBDBD'], > [""+<%=request.getParameter("ano2") %>, > <%=ventaAcumulada2%>, '#E6E6E6'], > > ]); > > var options = { > legend: { position: 'none' }, > bar: {groupWidth: "50%"}, > chart: { > title: ' ', > }, > bars: 'vertical', > vAxis: {format: 'currency'}, > height: 400, > colors: ['#BDBDBD', '#E6E6E6'] > }; > var chart = new > google.visualization.ColumnChart(document.getElementById("chart_div_acumulada")); > chart.draw(data, > google.charts.Bar.convertOptions(options)); > } > </script> > </td> > <td> > <div id="chart_div_proyectada" style="width: > 450px; height: 400px; padding-left: 50px;"></div> > <script type="text/javascript"> > google.charts.load('current', {packages: > ['corechart', 'bar'], 'language': 'es'}); > google.charts.setOnLoadCallback(drawChart); > function drawChart() { > var data = > google.visualization.arrayToDataTable([ > ["", "", { role: "style" }], > [""+<%=request.getParameter("ano1") > %>, <%=ventaProyectada1%>, '#BDBDBD'], > [""+<%=request.getParameter("ano2") > %>, <%=ventaProyectada2%>, '#E6E6E6'], > > ]); > > var options = { > legend: { position: 'none' }, > bar: {groupWidth: "50%"}, > chart: { > title: ' ', > }, > bars: 'vertical', > vAxis: {format: 'currency'}, > height: 400, > colors: ['#BDBDBD', '#E6E6E6'] > }; > var chart = new > google.visualization.ColumnChart(document.getElementById("chart_div_proyectada")); > chart.draw(data, > google.charts.Bar.convertOptions(options)); > } > </script> > </td> > </tr> > </table> > > Y solo se muestra la gráfica de la primera tabla > > ¿Alguna solución?
