* Convert axis options from arrays to objects * Updated all chart type defaults * Throw errors when axis type or position are not specified * Avoid raising unnecessary errors when merging options into the default configs * Fix additional tests * Ensure scale defaults are set if type is not explicitly defined * Another step * Include `scale` as `firstIDs.r` * update docs * Update for buildOrUpdateScales * Update migration guide * Add test back
