I have the same setup except my iMac sports Thunderbolt. I had the same problem and never solved it, but I did find the following work-around helpful:

Place the iMac in Target Mode by going to Apple|System Preferences|Startup Disk, make sure your startup disk is highlighted, select Target Disk Mode and confirm. Connect the computers by Firewire or Thunderbolt (TDM does not support Ethernet). Start Migration Assistant on the MacBook Pro, allow it to change your system, and select the iMac's startup disk.

From there it is easy sailing - choose what you want and how to handle the user accounts and you are home and dry! Don't forget to eject all connected iMac drives before unplugging the cables.

Hi I have a column chart with negative values which is showing wrong x-axes categories value. I'm sending a pre-build JSON array from the server , but no matter what i can't get the x-axes categories to show the right values.

Here is the code :

     var chart_data = JSON.parse(data).avg_range;


                        console.log(chart_data.x_axes);

                        var safety_chart_average = {
                            chart: {
                                type: 'column',
                                renderTo: pattern + '-safety-mini-chart-section',
                                spacingRight: 20,
                                spacingLeft: 20,
                            },
                            rangeSelector: {
                                enabled: false
                            },
                            navigator: {
                                enabled: false
                            },
                            scrollbar: {
                                enabled: false
                            },
                            credits: {
                                enabled: false
                            },
                            title: {
                                text: "Avg Changes",
                                marginBottom: -10
                            },
                            xAxis: {
                                categories: chart_data.x_axes
                            },
                            series: chart_data.prices


 };


This is what i'm getting



The x-axes is showing wrong values, as you can see from the picture above. 

But console.log(chart_data.x_axes) gives 
["Day 1", "Day 2", "Day 3"] which should be the correct x-axes label.

Please let me know how can i fix this x-axes label error.
